The Siren Board

One of the stations in the fire district I volunteer for recently retired this little baby HOR SiroDrone. The department made the switch over to pagers. One of the firefighters is taking it home to restore, after it will be returned to the department for historical value. Attached are some pictures. This thing is tiny, smaller than a model 2. It is 2HP, Single Phase, 8 ports. The one time I heard it, it was ungodly high pitched like that of a 2001, and was probably about as loud as a Firetruck Q siren.

That's surprisingly small.

Indeed, that is VERY small for a siren. Dang, pagers are over-rated. That chopper doesn't even look much bigger than that of my model L.

Looks like a Model 1 with an HOR cap.
